[Latin agnatus, past participle of agnasci, to become an agnate : ad-, +
nasci, to be born.]

"On April 17, 1907 Grand Duke William IV, last agnate of the senior branch
of the House of Nassau, father of six princesses but denied a male heir,
promulgated a family statute under which his eldest daughter, Princess
Marie - Adelaide, was declared heir presumptive to the Crown."

While English has one of the most expansive vocabularies among languages,
one area where it is easy to notice its impoverishment is in words to
describe relations. When you introduce a bright young fellow as your
brother-in-law, you don't really tell much. He could be any of the maybe
half dozen people in your kinship. On the other hand, many languages have
words to describe even the most complicated relation concisely and
unambiguously. In the Hindi language, for example, there are distinct words
to spell out all possibilities of brothers-in-law, and in some cases, there
are separate words depending on whether the bro-in-law is younger or older
than the person through whom this relationship takes place. At any rate, one
English term that doesn't leave any room for equivocation is mother-in-law.
